LOOM-SHUTTLE.

SPECIFICATION forming part 0f Letters Patent No. 403,979, dated May 28,1889.

Application filed March 26, 1888. Serial No. 268,476. (No model.)

To all whom, t may concern:

Be it known that I, FREDERICK K. WEIQHT, of Rochester, in the county ofMonroe and State of New York, have invented a new and useful Improvementin Loom Shuttles, of which the following is a specilication.

This invention relates to that class of shuttles which are usedprincipally in the manufacture of wire-cloth, and which are operatedpositively by two carriers arranged on opposite sides of the loom andalternately receivin g and delivering the shuttle-as, for instance, inLetters Patent No. 299,610, granted to me June 8, 1884.

The object of my invention is to improve the construction of the shuttlewith reference to the reception of the bobbin and the delivery of theshuttle-Wire; and my invention consists of the improvements which willbe hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my improvedshuttle. Fig. 2 is a horizontal section of the same. Fig. 3 is a frontelevation of the shuttle, showing the .hinged gate raised. Fig. 4 is avertical crosssection in line x, Fig. 2.

Like letters of reference refer to like parts in the several figures.

A represents the body of the shuttle, provided at opposite ends withpointed arms a a.

B represents the locking-lever, arranged in a recess formed in the rearside of the body A and arms a d', and constructed in any suitablemanner-for instance, as described and shown in my Letters Patent No.373,423, dated November 15, 1887.

C represents the bobbin of elongated cylindrical form, and having itsjournals c c arranged in the longitudinal direction ot the shuttle.

d d represent half-bearings formed in the body of the shuttle atopposite ends of the opening D, in which the bobbin is arranged, andreceiving the journals c c.

E represents a forwardly-projectng guideframe secured to thesl1uttle-body and composed of two converging arms, e e', having theirouter ends connected by a short horizontal bar, e2, upon which aremounted two guide-rollers, f f.

g represents aspringcatch, of any suitable construction, secured to theinner side of the arm e..

H represents a movable gate, composed of two converging arms, h 7L', anda longitudinal connectingbar, h2, similar in form to the correspondingparts of the guide-frame E of the shut-tlc -body, and adapted to rest onsaid guide-frame, so as to confine the bobbin in the shuttle. The gate His hinged to the shuttle-body by pivots '11, and its longitudinal pieceh2 is provided with openings i', which it over the studs oftheguide-rollers f when the gate is closed. The gate is provided on itsupper side with a notch, j, in which the head of the spring-catch gengages when the gate is closed, thereby locking the latter on the frameE. The gate II is provided With recesses le 7c, which close over thejournals of the bobbin and hold the latter in its proper position in theshuttle.

L represents a flat tension-spring, secured at its middle to the innerside of the rear portion of the shuttle-body and bearing with its endsagainst the flanges Z l of the bobbin.

M is a longitudinal bridge or depressed guard, formed on the under sideof the shuttile-body underneath the bobbin, for the purpose ofpreventing the Warp Wires or threads from coming in contact with theunder side of the bobbin, and N is a similar bridge formed on the upperside of the gate ll.

Upon unlocking the gate and raising the same thebobbin is easilyinserted or removed and the bobbin Wire or thread placed between theguide-rollers ff. Vhen the bobbin has been placed in the shuttle, it issecured therein by simply closing the gate, which is locked by thespring-catch. The tension is the same in both directions of the movementof the shuttle, as the axis of the bobbin is arranged in the directionof this movement and the wire is fed out in either direction at the samepoint. The bobbin-wire is, therefore, not liable to be cut or broken,and light or Weak Wire can be successfully Woven by the use of thisshuttle.

I claim as my invention- 1. The combination, with the shuttle-bodyhaving sockets for the bobbinhjournals and provided on its front sidewith a projecting horizontal guide-frame, E, of a movable gate IOOcovering said guide-frame and attached to the shuttle-body by pivotsarranged lengthwise of the shuttle, substantially as set forth.

2. The combination, with the shutt1e-body provided with sockets for thebobbin-journals and having a projecting guide-frame, E, provided withguide-rollers ff, of a movable gate covering said sockets andguide-rollers, substantially as set forth.

3. The combination, With the shuttle-body provided with sockets for thebobbin-journals and having a guide-frame, E,of a movable gate attachedto the shutt.1 e-body, a depressed guard, M, formed on the under side ofthe Shuttle-body, and a raised guard, N, formed 15 Y on the 'movablegate, substan tially as set forth. Vitn ess my hand this 19th day ofMarch,
